For this japanese Torii, i sculpted my model in Blender. I wanted to test a "bas relief" to decorate a wall. Here's a screenshot of my viewport : 

I printed it in one piece on my Elegoo Neptune 3 Pro with PLA. The Torii is 15cm tall. 26h of printing.



Then i painted it with acrylic. 

You can get the .stl to print it yourself here
